I think Google translate relies on parallel texts to help build its algorithms. While there are lots of Latin/English parallel texts out there, I suspect a lot of them aren't going to be very useful. Sure, the Aeneid is online. Sure, Dryden's translation is online too. I bet they're even closely associated. But would they be close enough to each other to give a starting point?

Once you've got the starting point, is there enough supporting data to refine the process?

To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it. Or desires to obtain pain in the bullet train to find fault with in the pleasure of pain that produces no resultant good to flee. These cases are perfectly account of the system, the fault of those who are in the original text: this is to sink."
